The major pig diseases on large-scale swine farms have plagued the swine industry at the time, and it has been difficult to diagnose and determine the time for various primary pathogen infections, which has brought difficulties to the prevention and control of the disease. Multiple infections and mixed infections have become a common phenomenon in China's large-scale pig farms.
In order to control multiple infections, a few large-scale pig farms have introduced foreign new technologies such as multi-point rearing, early weaning, weaning, and secondary conservation. Most pig farms are still unable to do anything and even lose confidence in healthy breeding. The use of various high-quality vaccines and drug-based health care methods and immune reinforcement are also difficult. The reason for this consequence is that it is unclear why the disease has occurred.
At present, the prevention and control of diseases in foreign swine farms has progressed from the group treatment stage to the individual treatment stage, while China is still in the stage of the original universal drug- and vaccine-prevention stage, and there are quite a number of large-scale swine farms in immunization. Failure and group stage disease treatment.
This stage of complex infection has constituted a background disease. Why is there such a serious risk of illness?
There are three reasons for this: The first is that the entire husbandry and management and environmental management are not in place. Extensive management puts too much stress on the pigs. The second is that the mycotoxin has a large impact on the pigs and causes pigs to lose their resistance; The third type of swine disease introduced new pathogens or infection pressure around the disease.
Knowing the reasons, we will know the way out. The solution is still threefold: first, to strengthen management; second, to strengthen management; third, to strengthen management.
There are many examples that have shown that the same pigs and the same disease background will not develop as long as they are well managed, whether it is Haemophilus parasuis, PRRS, or circovirus infection. Therefore, the core of mixed infection control is to strengthen management. Improve environment, nutrition and biosecurity through management.
Indiscriminate use, abuse, and misuse of vaccines and drugs must be strictly managed and corrected to prevent the use of non-standard drugs. The farm must establish a standardized pig management system, summarize the key control points in the pig production process, cultivate employees according to these key points, and enable employees to perform standardized operations based on these key points so that pigs can be used in the production process. Being able to receive less stress and not be affected by stress has a remarkable effect on pig disease control.
During pig rearing, we must always pay attention to the dynamics of pigs. On large-scale farms, we require four serological tests a year, mainly antibody detection for swine fever and swine pseudorabies, and detection of Toxoplasma gondii for respiratory diseases. General pig farms can be managed through fine management, and real solutions to management problems must be analyzed through production level data.
